Description
Technical field
The present invention relates to a kind of energy dissipation apparatus and job practices thereof of building structure, particularly a kind of power consumption support system and job practices thereof of consume energy steel plate and diagonal brace composition.
Background technology
Because metal material enters plasticity and has good hysteresis performance later on, thereby is used to make various types of energy-dissipating devices.A kind of passive energy-consumption shock-absorption device that steel plate energy consumer device is generally assembled by low-yield or the high ductility steel plate of extremely low yield point and its positioner.Its antidetonation mechanism is simple, cost is low, effect is remarkable.Simultaneously, this device generally is to be installed in the structure as nonload bearing element, and under normal operating condition, it can improve the integral rigidity of structure; Under little earthquake situations condition, building structure itself just can be satisfied requirements for fortification against earthquake, and this moment, the distortion of structure was less relatively, and the steel plate energy consumer does not enter or enters the plastic stage than small part; When running into big shake or rarely occurred earthquake, energy consumer will rate be introduced into the plastic stage, relies on the plasticity of its generation can reduce the earthquake response of structure, and its destruction can not influence integrally-built use.The seismic design that this device both can be used for the new construction structure also can be used for the reinforcing maintenance of existed building, has good economic benefit.
The steel plate energy consumer can be divided into inplane shear type and out-of-plane bending type according to its stress form.In-plane bending shaped steel plate energy consumer has the advantage that ductility is good, hysteresis loop is full, but its initial stiffness less, have the metallic film effect, when mounted, the multi-disc steel plate is installed side by side often, its steel using amount is bigger; For inplane shear shaped steel plate energy consumer,, often need comparatively strict geometry and higher processing technology and make that its cost is higher for in-plane stress is more evenly distributed, hysteresis loop is fuller to give full play to the performance of steel.Simultaneously, in case history in the past, majority be pay attention to pursue steel plate energy consumer itself mechanical property performance and ignored the effect of its braced structures, cause the rigidity of braced structures of many energy consumers own less, can not bring into play the due effect of braced structures, thereby it is later relatively to make that mounted steel plate energy consumer enters time of plastic state, and its power consumption effect performance is not enough.
Summary of the invention
The purpose of this invention is to provide power consumption support system and job practices thereof that a kind of consume energy steel plate and diagonal brace are formed, solve the power consumption steel plate because of the unfavorable technical problem of effect that causes consuming energy of flexing outside the plane.
For achieving the above object, the present invention adopts following technical scheme:
A kind of power consumption support system of consume energy steel plate and diagonal brace composition, be arranged at the rectangular area that structural beams and structural column surround, comprise put more energy into power consumption steel plate and two-way bearing diagonal, the described power consumption steel plate of putting more energy into is made up of power consumption steel plate and the stiffener that is arranged on the frame steel plate around it and is arranged on power consumption steel plate two sides, and the described steel plate that consumes energy of putting more energy into is arranged on the end face of two-way bearing diagonal by connector.
Described stiffener is stuck in the angle of power consumption steel plate and the formation of frame steel plate, is connected by weld seam with the frame steel plate.
Described two-way bearing diagonal is that herringbone bridging or A font support.
On the described structural beams girth member is set.
Described girth member is channel-section steel, steel plate or angle steel.
The job practices of the power consumption support system that described power consumption steel plate and diagonal brace are formed, step is as follows:
Compared with prior art the present invention has following characteristics and beneficial effect:
The power consumption support system that power consumption steel plate of the present invention and diagonal brace are formed had both had the effect that ordinary steel supports, and had the effect of power consumption again.Can increase the integral rigidity of building structure when under normal condition, using; and when running into earthquake; the steel plate energy consumer will be introduced into yield situation than structure and diagonal brace; utilize the surrender power consumption of steel plate energy consumer can reduce the earthquake response of building structure, building structure is played a very good protection.
The power consumption system of described put more energy into power consumption steel plate and diagonal brace composition, the power consumption steel plate initial stiffness of putting more energy into is big, its steel surrender area is big, power consumption is effective, steel utilization ratio is high owing to the outer flexing of face is restricted, and making, the installation of while steel plate energy consumer are simple and convenient, and cost is lower; The diagonal brace initial stiffness is bigger, can better bring into play its due effect, has changed diagonal brace insufficient rigidity or the bigger defective of rolled steel dosage in the past.
The stiffener of power consumption steel plate of putting more energy among the present invention only welds mutually with the frame steel plate, when stiffener plays the outer flexing of face to the steel plate that prevents to consume energy, can not have a negative impact because of the mechanical property of welding to the steel plate that consumes energy.
Applicability of the present invention is strong, both has been applicable to that steel work also is applicable to concrete structure; The design that both can be used for new construction also can be used for the reinforcing maintenance of existed building.
The present invention can be widely used in the energy-dissipating and shock-absorbing of steel frame, concrete frame structure.
